Hi Konrad, Does this look at all familiar? There is some more info in the full bug log at http://bugs.debian.org/637234 . In particular, contrary to the message below, the user subsequently confirmed that the issue appears to be Xen specific (doesn''t happen on native or vmware) and that it arose between 2.6.39-2-686-pae and 3.0.0-1-686-pae. Could it be related to edf6ef59ec7e

I just tried this with CentOS 5.3 as well, and got exactly the same symptoms and dmesg output. (As a point of comparison, Ubunu 8.04 on my work laptop is able to access the drive.) Obviously "not detected" is a misapprehension, though I'm puzzled why "lsusb" doesn't show it. The device is there even though the partition table can't be read. ---------- Forwarded

Hi, Sorry for the need of the long winded email. Looking for some answers to the following. I am setting up a xen PV domU on top of a LVM partitioned DRBD device. Everything was going just fine until I tried to test the filesystems in the domU. Here is my setup; Dom0 OS: CentOS release 5 (Final) Kernel: 2.6.18-8.1.4.el5.centos.plusxen Xen: xen-3.0.3-25.0.3.el5 DRBD:

Hey all, I''m trying to figure out how to re-size physical partitions in the Dom U. I''ve read up what I can find on line and finally decided to have Logical Volumes in the Dom 0 and pass them as physical volumes for use in the Dom U. Here''s an example of what I''m doing. To start in the Dom 0 I created the LV''s with lvcreate -n guest_boot -L 100M

Hi there, I have some data which are convenient to enter as lists. For example: t1<-list(fname="animal1",testname="hyla",dspkr="left",res1=39.7,res2=15.0) t2<-list(fname="animal1",testname="bufo",dspkr="left",res1=14.4,res2=56.1)

Hi All, I had to reboot a machine as I lost the ssh connectivity to it. I could ping to it though. On rebooting, the dmesg buffer showed the following messsage hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error } hdc: dma_intr: error=0x40 { UncorrectableError }, CHS=7520/0/155, sector=1820440 end_request: I/O error, dev 16:02 (hdc), sector 1820440 hdc: dma_intr: status=0x51 { DriveReady

Dear R-users, I would like to maximize the function g above which depends on 4 parameters (2 vectors, 1 real number, and 1 matrix) using optim() and BFGS method. Here is my code: # fonction to maximize g=function(x) { x1 = x[1:ncol(X)] x2 = x[(ncol(X)+1)] x3 = matrix(x[(ncol(X)+2):(ncol(X)+1+ncol(X)*ncol(Y))],nrow=ncol(X),ncol=ncol(Y)) x4 = x[(ncol(X)+1+ncol(X)*ncol(Y)+1):length(x)]

Hi R helpers! I have a question. I'm trying to create a function for an exercise. Here are the arguments I should include: x and y are numeric z is a name ("plus","minus","multiply","divide") and swap is logical. Here is what the function should do: When z="plus", then x+y is performed and so on for the other z names. It should give a NA

Hi, There is an opportunity in instCombine for following instruction pattern: %mul = mul nsw i32 %b, %a %cmp = icmp sgt i32 %mul, -1 %sub = sub i32 0, %a %mul2 = mul nsw i32 %sub, %b %cond = select i1 %cmp, i32 %mul, i32 %mul2 Source code for above pattern: return (a*b) >=0 ? (a*b) : -a*b; Currently, llvm(-O3) can not recognize this as abs(a*b). I initially think we could do this in

Hi Roman, Thanks for your good idea. I think it can solve the abs issue very well. I can continue with my work now^-^. But if it is not abs and there is no select, %res = OP i32 %b, %a %sub = sub i32 0, %b %res2 = OP i32 %sub, %a theoretically, we can still do the following transform for the above pattern: %res2 = OP i32 %sub, %a ==> %res2 = sub i32 0, %res Not sure whether we can do it

Hi, I have a program written in R which is good on the version 1.2, but for the fallowing versions of R, an error always is at the same place. That is at the level of the fallowing line: Sur<- getInitial(res2[m:M,2]~SSasymp(res2[m:M,1],Asymp,resp0,lrc),data=res2) Error in eval(expr,envir,enclos):numeric envir arg not of length one I don't know at all this langage for the instant.

I am using R 1.1 with Redhat 6.2 and RW 1.001 with Win98 (the upkey doesn't work on my IBM either as has been previously reported by others). The function aov doesn't return either the residuals or the residual degrees of freedom for split-plot designs. If you use the following code from Baron and Li's "Notes on the use of R for psycology experiments and questionnaires"

Hi - relatively inexperienced user here. I installed CentOS 5.2 yesterday (http install via a mirror, worked brilliantly), as well as a new Seagate 1Tb USB external HDD (from the new Xtreme line), for backup/media storage. Using fdisk I put two primary partitions on the Seagate, /dev/sde1 and /dev/sde2 (roughly half the drive each). Then I used mkfs.ext3 on both to create ext3 filesystems
